GENERAL DESCRIPTION The subject of this invention is a special type ofsemi-automatic machine for forming a counterboring in one end of a smallmachined part (in this particular case the nose or fuse portion of aprojectile), placing a pellet or disk of metal in the counterboring thusformed, swaging or crimping over the end of the fuse to retain thepellet in the counterboring, and finally ejecting the processed fuse.

As presently constructed, the machine has an operating cycle comprisingfive steps or stages and is arranged to process four identical parts atone time in each stage of the operating cycle.

In the first stage of operation, the fuses are hand-loaded into suitablenesting recesses located in a turntable which carries said fuses throughthe different stages of operation, and in the second stage of operationthe machining of the counterborings tak'es place. In the third stage ofthe operating cycle, pellets are fed from a hopper or magazine, wherethey are stored, and

placed in the counterborings, and in the fourth stage of operation theupper ends of the fuses are crimped over adjacent to the counterboringsto secure the pellets in place therein. Also during the fourth stage ofthe operating cycle, and occurring simultaneously with the crimping ofthe.

fuses, identifying data is stamped on the outer circumference of saidfuses near the base thereof. In the fifth stage of the operating cycle,the completed fuses are picked out of the recesses in the turntable anddeposited in a chute which conveys them to a suitable container.

The turntable which carries the fuses through 1 the different stages ofoperation has five sets of recesses, corresponding to the five stages ofoperation, and each set comprises four recesses. Thus it is seen thatfour of the parts may be processed during each stage of operation.However, the number of parts processed at each stage doubtedly themachine could have been arranged to automatically load the parts to beprocessed into the recesses in the turntable; however, this was believedto be unnecessary because, to insure proper operation of the machine,the constant presence of an attendant is necessary, and it is likewiseof vital importance that the parts be properly placed in the recesses ofthe turntable in order to insure the necessary accuracy in theprocessing of said parts.

The turntable is connected to a main driving motor by a Geneva geardevice, which device intermittently rotates said turntable, and theparts to be processed by the machine, through the five stages of anoperating cycle, in proper timing. Cams, driven by the main operatingmotor, control the timing and the operation of the counterboring, thepellet assembling, the crimping and stamping, and the ejectingmechanisms.

In the ensuing pages, a detailed description will be given of themachine of this invention, said description including repeated referenceto the different figures of the drawings, in which like referencenumerals refer to like parts.

DETAILED Dnscnn-non Framework and turntable Directing attention to Figs.1, 2, and 5, the framework of the machine of this invention comprises atop plate 40 and a bed or base plate 4| said plates being secured inparallel relationship to each other by uprights 42 to 45, inclusive,secured respectively to the outer edges of said plates 40 and 4|. Themachine is supported on a suitable foundation by four similar legs 45(Fig. 1) secured to the bottom of the base plate 41. The top plate 40(Figs. 1 and 2) has therein a circular opening, through which extends atumtable 41, the top surface of which is fiush with the top surface ofthe plate 40.

The turntable 41 (Figs. 1, 2, and 3) has in the center thereof a boring,which fits over a tenon on a flange 48, said flange being secured to.said table by a plurality of screws 49. A boring in the center of theflange 48 fits over a tenon (Fig. 3) on the upper end of a spindle 50. Akey 5| secures the flange 48 and the spindle 50 in fixed relationship toeach other. The flange 48 is held against a shoulder, formed on thespindle 50 by the tenon on the upper end thereof, by a nut 52,

which threads on the extreme upper end of saidagainst rotation by a. key55. A thrust washer 56,

interposed between the flange 48 (Fig. 3) and a top surface of thecasting 54, forms a frictionreducing bearing between said flange andsaid casting. Keyed to a tenon formed on the lower end of the spindle 50(Figs. 3 and 6) is a Geneva gear 51, which is held against the shoulderformed by said tenon by a nut threaded on the extreme lower end of saidspindle 50.

The Geneva gear 51 has therein five equally spaced notches 58 (Fig. 6)adapted to be engaged by a driving roller 59 mounted on the face of adriving disk 60 secured on a shaft 6|. Integral with the disk 50 is alocking plate 62, the periphery of which cooperates with arc-shapedrecesses 63, equally spaced between the notches 58 in the Geneva gear51, to lock said Geneva gear, the spindle 50, and the turntable 41against move- Clutch mechanism Secured on the lower end of the verticalshaft n (Figs. 4, s, and 17) is a driven'member st of a clutch, saidmember having in one face thereof teeth adapted to be engaged bycorresponding teeth in a clutch driving member 65 slidably supported ona flanged sleeve 66 freeon the shaft 6|. Keys cooperating with slots inthe clutch driving member 65 and the sleeve 66 permit engaging anddisengaging sliding movement of said member, but connect said member 65to said sleeve 66 forrotary movement in unison therewith. The upper endof the shaft 6| (Fig. 1'!) is journaled in a bushing in the base plate4|, while the lower end of said shaft is journaled by means of thesleeve 66 in cooperation with a bushing in a Geneva gear housing 68'secured to said base plate 4|. A flange 61 of the sleeve 66 (Figs. 6 and17) is secured in a counterboring in the upper face of a helical gear69, the teeth of which cooperate with a worm gear 10 secured on a shaft1| journaied in suitable bushings in the housing 68. The shaft 1| (Fig.6) is connected by a coupling member 12 to an armature shaft 13 of amotor 14, which motor is preferably secured to the base plate 4|, butmay, if desirable, be mounted on the foundation which supports the legs46 (Fig. 1) of the machine.

The clutch driving member (Figs. 1, 4, and 17) has therein an-annulargroove 15 adapted to be looseLv engaged by two identical studs 16 in twosimilar upward extensions 11 of a clutch disengaging member 18, saidmember 18 having therein a central boring which flts freely on a reducedportion of the clutch driven member 64. A downward extension of themember has therein a slot adapted to receive the rearward end of a lever19, said rearward end being pivotally mounted in said slot by a studcarried by said member 18. The lever 19 likewise passes through a slotin a downward extension of a support 84 and is pivoted on a stud 85carried by said support. The support 84 has a tenon, which is threadedinto a boss 86 formed on the housing 66, and said tenon and a spring arm81, free thereon, are locked in place by a lock nut 88. A spring 89,tensioned between the spring arm 61 and the lever 19, urges said leverin a clockwise direction (Fig. 4) to normally maintain the clutchdriving member 65 in engagement with the clutch driven member 64. A footpedal 90 on the left-hand end of the lever 19 provides means foroperating the lever counter-clockwise, against the action of the spring89, to .disengage the clutch driving member 65 from the driven member64, to disconnect the shaft 6| and mechanism secured thereon, includingthe Geneva gear driving disk 60 (Figs. 6 and 17) and the Geneva gearlocking plate 62, from the driving motor 14, when it is necessary ordesirable.

The table 41 (Figs. 2 and 12) has therein five sets of holes 9|, eachset corresponding to one of the five stages of an operating cycle, andeach hole has fast therein a bushing 92 adapted to receive the threadedtenon of a projectile fuse 93 The motor 14 and the gearing shown inFigs. 6 and 17 cause the Geneva gear 51 (Figs. 2, 3, and 6) to rotatethe table 41 in a counter-clockwise direction, as shown in Fig. 2, tocarry the different sets of bushings 92, and the fuses 93 insertedtherein, progressively from one station or stage of the operating cycleto another, and

toretain said fuses in said stations a sumcient 1 length of time for themachine to automatically perform the machining and assembling operationson the fuses. By referring to Fig. 2, it will be seen that the fivestations are numbered I, 2, I. 4, and 5 progressively acounter-clockwise direction around the table 41,-and will hereinafter beused in identifying the different stages of the operating cycle and inexplaining the mechanism associated with each of said stages ofoperation. I

As each of the flve sets of bushings 92 (Figs. 2 and 12) is brought tostation I, the holes in said bushings'are loaded with four of theprojectile fuses 93, as here shown. This loading is effected by anoperator, who manually places said fuses in the holes in said bushings,and this con-, stitutes the only manual portion of the operation of themachine, "as thereafter themachine functions automatically toperformthemachining and assembling operations on the fuses 93, at the completionof 'which the iinished fuses are antomatically lifted" from the bushings92 and deposited in a chute which guides said fuses to a suitablereceptacle.

Figs. 22, 23, 24, and 25 show the fuses 93in the different steps orstages of the operating cycle. Fig. 22, for example, shows the conditionof the fuses 93when they-are hand-loaded into the holes in the bushings92 at station I (Fig. 2) in the first step or stage of the. o ration.

Fig. 23 showsthe condition of the fuses 93 at the completion of thesecon'dstage of the operating cycle, which is performed at station 2 andin which a counterboring 94 is machined in the upper ends of said fuses.U

Fig. 24 shows the condition of the fuses 93 at the completion of thethird stageof operation, which is performed at station 3 and in which asmall metal pellet 951s automatically inserted in each of thecounterborings 94. i

Fig. 25 shows the'condition of the fuses 93 at the completion of thefourth stage of the operating cycle, which is performed'at station 4 andin which the upper edges or rims-of the counterborings 94 are crimpedover, as shown at 96,

to secure the pellets 95 in said counterborings.

Inthe fifth stage of the operating cycle, which is performed at station5, the completed fuses 93 are lifted from their nesting holes in thebushings 92 and deposited in a chute which guides them to a suitablereceptacle.

The drive of the motor 14 (Figs. 5, 6, and 17) is transmitted to thedifferent mechanisms of the machine through a gear 91 secured on theshaft 6|, said gear 91 meshing with an idler gear 98 free on the sleeve53 (Figs. 3 and 5), which rotatably supports the spindle 50. The idlergear 98 meshes with and drives similar gears 99, I00, and IOI free onrods I02, I03, and I04, the lower ends of which are secured in the baseplate 4| (Figs. 1 and 5) and the upper ends of which'are supported bythe casting 54.

a slot I09 in a bracket secured to the upright 42. The block I08 hasthreaded therein the lower 0 end of a rod III, the upper end ofwlcich issetical sliding movement by the pins I39 and I40,

and the rod III passes through guide holes in the top plate 40 and theplate I,

- The casting II3 (Figs. 1, 9, and 11) rotatably supports four identicalspindles II4, the upper ends of which spindles are keyed in bushings II5 journaledin borings in a casting II6 secured to the-upper ends of thepins I39 and I40. While the spindles I I4 rotate in unison with said-bushings, still they are free to slide vertically therein, as thecasting II3 is lowered and raised to counterbore the fuses 93. Eachofthe bushin s II5 (Figs. 9 and 10) hassecured to the upper end thereofa worm gear II1, which meshes with a companion worm gear II8 secured ona shaft II9 joumaled in the casting II6. Secured on the right-hand endof the shaft H9 is a pulley I connected by a belt I2I to a similarpulley secured on the armature shaft of a motor I22 mounted on a bracketI23 secured to the upright 42.

Each of the spindles II4 (Figs. 9, 11, and 12) has secured on the lowerend thereof a drill chuck I24 having clamped therein a counterboringtool I25, which extends through a clearance hole in a bushing I26secured in a pressure plate I21 slidably supported by a pair of studsI28 and I29 threaded into the casting II3. Compressible springs I30 oneach of-the studs I28 and I29 urge the correspondingpresshre plate I21downwardly, which downward movement'is terminated by heads on said studsI23 and I29. The pressure of the springs I 30 (Fig. 9) may be adjustedby means of adjusting and locking nuts threaded on the studs'IZIl andI29. Each of the bushings I26 (Fig. 12) has clamped in a central boringtherein an annular type of ball bearing, the center bushing I33 of whichforms a guide for the corresponding counterboring tool I25. The bushingI33 is centrally located in relation to a conical boring I34 in thebushing I26, which boring conforms in shape to the external surface ofthe fuse 93.

threaded in a bar I36 secured to the cross bar H2 of the casting I I3,said stop screws I35 adapted to be locked in adjusted position by meansof lock nuts I31 after said stop screws have been adjusted-in relationto corresponding stop studs I39 secured in the plate- I4I, thusproviding means, independent of the cam groove I06 and associated parts,for accurately determining the depth of the counterborings in the fuses93.

Pellet feeding and placing mechanism After the counterboring operationhas been completed at station 2, the table 41 is indexed by the Genevagear mechanism shown in Fig. 6 and described above, to transport saidfuses to station 3, where the metal pellets 95 are inserted into Thepellet-inserting I mechanism will now be described.

Secured near the upper end of the shaft 6I (Figs. 8 and 17) is a diskI42 having in the pe- The cam I46 (Figs. 5, '7, and 1'7) has therein acam groove I41, which is engaged by a roller. I48 rotatably supported bya stud in a slide I 49 free in a rectangular opening formed by platesI50 and I5I secured to the main top plate 40. The slide I49 (Figs. 5, 7,14, and 1'7) has secured thereto an upright I52, the upper end of whichextends into a recess in a rack I53, and said upright I52 is grippedbetween adjusting screws I54 and I55 threaded in said rack I53, toprovide a means for adjusting said parts in relation to each other.

The rack I53 is slidably mounted in a slot formed by plates I56 and I51(Figs. 14, 15, and 17), and the bottom of said rack bears on the topsurface of a plate I 58, to which the two plates I56 and I51 aresecured. The plate I58 is in turn Rotation of the gear 99 (Figs. 5 and9) and the drum I05 causes the cam groove I06, operating according tothe time given in space I, Fig. 29,

and in cooperation with the roller I01, to shift the slide block I08,the rod III, and the casting II3 downwardly. Downward movement of thecasting II3 carries the plates I21 and the bushings I26 in unisontherewith until the borings I34 engage the noses of the four fuses 93awaiting operation at station 2. The borings I 34, due to the pressureplates I21 and the springs I30, firmly grip the fuses 93 before thecounterboring tools I25 contact said fuses, so that said fuses will beheld against rotation while the counter- Continued downward movement ofthe casting II3 compresses the springs I 30 and causes the counterboringtools I25 to form the counterborings 94 (Fig. 23) in said fuses'93.After the counterborings have been machined in the fuses 93, continuedrotation of the gear 99 causes the cam groove I06 (Fig. 9 and space I,Fig. 29) to restore the secured to the main top plate 40, and theupright I52 passes through clearance openings in the plates I5I, 40, andI58 (Fig. 17). p

The rack I53 (Figs. 13, 14, 15, and 17) meshes with two similar gearsI59 and I60 secured, respectively, on shafts I 6I and I62 journaled inuprights I63 and I64 in-tum secured respectively to the plates I56 and I51. Secured on each end I of the respective shafts I6I and I62 areidentical cranks I65 and I66 carrying, respectively, studs I61 and I68,which freely engage corresponding borings in hangers I69 and I10 securedto the bottom surface of a plate I1 I.

Rotation of the cam I46 in unison with the shaft 6| in a clockwisedirection, as observed in Fig. 5, causes the groove I41, operatingaccording to the time given in space 3, Fig. 29, to move the slide I49,the upright I52, and the rack I53 (Figs. 14, 1'7, and 18) first in adirection away from the center of the machine or toward the right ashere observed. Initial movement of the rack I53, through the gears I59and I60, revolves the shafts I8I and I82 and the cranks I88 and I88first in a counter-clockwise direction (Figs. 1'! and 18), causing saidcranks to oscillate the plate "I also in a counter-clockwise directionto place'the pellets 88 in the counterborings 88 in the fuses 88, aswill be explained later. Continued movement of the cam I88, through themechanism just described, causes the plate I" to be oscillated clockwiseback to normal position, as shown here, after the pellets have beendeposited in the counterboringa Secured to the top surface of the plate"I (Figs. 13, 14, 17, and 18) are four similar racks I12, which meshwith their respective gears I18 for each of the four pellet feeding andinserting mechanisms. Each of the gears I18 is free cn'a reduced portionof a corresponding pellet guide or magazine tube I18, a tenon on thelower end of which is secured in a boring in the plates I88 or I81. Eachof the gears I18 has a clutch. cut I18 in the upper end thereof adaptedto receivetenons on the lower end of a corresponding agitator tube orsleeve I18 free on the reduced portion of the tube I18 and also free ina'boring in a depending portion of .a pellet hopper I11 supported .bytwo similar brackets I18 (Fig. secured to the top surface of the table88.

Each of the sleeves I18 (Fig. 18) has on the upper end thereof anagitator extension II18, which extends into a funnel-shaped portion ofthe hopper I11.

Oscillation of the plate "I in the manner explained above causes theracks I12 in turn to oscillate the gears I18, the sleeves I18, and theagitator extensions II18 back and forth to agitate the pellets 88 sothat they will feed downwardly into a central-boring in each of thetubes I18 in an orderly manner and without clogging up the mouths ofsaid tubes. The pellet feed tubes I18 extend through clearance openingsI18 (Figs. 13 and 18) in the plate "I. By referring to Fig. 18, it willbe noted that the gear I18 is long enough in relation to the rack I12 topermit oscillating movement of said rack and the plate I'll.

A plurality of sight apertures III (Fig. 18), located near the lower endof each of the tubes I14, permits viewing the central boring of saidtubes to determine whether or not the pellets 88 are feeding andstacking up properly therein.

Pellet feeding slides Each of the four pellet feeding and assemblingheads I11 has a slide I82 (Fig. 18), which is actuated by the plate I1I,for pushing the pellets 88, one at a time, from the central borings inthe magazine tubes I18 into alinement with the pellet placing orassembling mechanism, which later picks up said pellets and places themin the counterborings in the upper ends of the fuses 88.

. Referring now to Figs. 14, 16, 1'1, and 19, the plate I1I has securedtherein a bushing I83 for each of the pellet assembling heads, each ofwhich bushings is a slip fit on a corresponding stud I84 having atapered head I88 formed on the lower end thereof, adapted to be engagedby Jaws formed in levers I88 and I81 of a pincertype clamp. The leversI88 and I 81 are pivoted V on corresponding studs carried by thecorreably supported in a corresponding slot formed in the plate I88,said slot likewise having secured in the bottom thereof a correspondingsupport 1 plate I 88, upon which the slides I82 rest. The slides I82 areapproximately the same thickness as the pellets '88 and slide freely inthe grooves in the plate I88 and between the top surface of thecorresponding support plate I88 and the lower surface of the plates I88or I81.

Counter-clockwise rotary movement of the plate I" (Figs. 13, '14, 16,and 18), as explained above, by means of the bushings I88 in cooperationwith the studs I88 and the spring clamps formed by the levers I88 andI81, carries the slides I82 toward the center of the machine or towardthe left, as viewed in Fig. 18, in unison therewith. This movement ofthe slides I82 causes a V-shaped centering notch I88 in the forward endsof said slides to engage the lowermost pellets 88in the tubes I14 andpush said pellets forwardly out of the slots formed by the top surfacesof the support I88 and the bottom surfaces of the plates I88 or I81,,toa predeter-, mined position on the forward ends of said supports I88, asshown in Fig. 14., This locates the pellets 88 in position to beproperly engaged by the pellet lifting and placing mechanism, whichmoves in unison with theplate Ill and which, at the time the pellets arepushed forward by the slides I82, is in its counter-clockwise position,away from the supports I88.

In their initial movements forwardly, the slides I82 (Fig. 18) pass overthe lower ends of the tubes I14 and thus close the openings in saidtubes.

Return movement of the slides I82 away from the center of th machine, ortoward the right,

as viewed in Fig. 18, leaves the pellets 88 in proper position on thesupports I88 to be engaged by the pellet lifting and placing mechanism,and

the movement of the notched portions I88 (Fig. 19) of said slides beyondthe lower ends of the tubes I14 permits the lowermost pellets to dropdown into position to be pushed forward by said 1 slides I82 in theirnext operation.

when the slide I82 of the one of the four units shown in Fig. 18, whichslide will hereinafter be used as representative of all four units, andthe plate "I are returned clockwise to normal position, as shown here, acountersunk boring I82 in a sleeve I88 comes .to rest over the pellet88, which has just been. moved forward by the slide I82, as explainedabove. The sleeve I88 fits freely in borings in a cross bar of a bracketI8I, secured to the plate "I, and a boring in said plate "I, saidborings being in vertical axial alinement. A compressible spring I 98,which fits over a reduced portion of the sleeve I83 and between ashoulder formed by said sleeve and the bottom surface of the plate I",urges said sleeve I88 downwardly, which downward movement is determinedbyan adjustable collar I88 secured sponding slides I82, and the jawsformed by said 16 an 19) form a yieldable connection between on theupper end of said sleeve. A screw I88, threaded in the front edge of theplate "I, has a tenon which engages a vertical slot in the sleeve I88 toprevent turning of said sleeve.

The sleeve I88 (Figs. 15, 18, and 24) has a central boring, which freelysupports a tube I81 having an enlarged head I88 on the lower end tion ofsaidsleeve193. 'A leaf spring I99, which is anchored near its centerbetween a collar and the head of a screw stud 200 threaded in the plate"I, has in opposite ends thereof holes which freely slip over theadjacent pair of tubes I91, said ends being clamped between similaradjustable collars-2M secured to said tubes I91. The spring I99-istensioned tourgethe tube I91 (Fig.18) downwardly to cause the enlargedhead I98 to yieldingly engag the pellet 95 when the parts are intheposition shown here.

Flexible tubing 202 (Figs. 15 and 18) connects each of the four'tubesi91 to a Venturi tube 203 secured to the hopper casting I11. A tube 204connects the Venturi tube to a valve 205 (Figs. and 11). A tube 201(Fig. 11) connects the valve 205 to a supply source ofcompressed air.The valve 205 is operated by a plunger 209(Figs. 10 and 11) incooperation with a camming surface 209 on an extension of the bar I39.

While the sleeve I93 (Fig. 18) is in position over the pellet 95, asshown'here, downward movement of the counterboring framework II3 (Figs.10 and 11) causes the camming surface 209, in cooperation with theplunger 208, to open thereof, which fits freely in a counterboredporsleeve starts its upward movement, to insure that said pellet 95 doesnot for any reason stick in said conical boring.

:C'rimping and stamping mechanism After the pellets have been placed inthe counterborings, as explained above, the Geneva gear mechanism shownin Fig. 6 functions to index the table 41- (Figs. 1 and 2) to advancethe fuses from station 3 to station 4, where the upper ends of saidfuses adjacent the counterborings 94 are crimped over, as indicated at'96 (Fig.

to secure the pellets 95 in the counterborings 94.

By referring to Fig. 5, it will be recalled that the gear I00 is drivenby the idler gear 93, which, through the gear 91, the shaft GI, and theworm gearing shown in Figs. 6 and 17, is driven by the motor 14.

The gear I00 (Figs. 1, 5, and 20) has integral therewith a drum-shapedportion 2I2 having therein a camming slot 2I3 engaged by a roller 2I4rotatably supported on the end of a pin 2I5 the valve 205 according tothe time given space 2, Fig. 29, to permit compressed air to flowthrough the tube 201 and 204 to the Venturi tube 203 at high velocity.The upward blast of air through the Venturi tube 203 creates a suctionor a partial vacuum in the tube 202, causing the pellet 95 to be heldfirmly against the head I90 of the tube I91 so that said pellet will bepicked up and carried counter-clockwise in unison with the sleeve I93and the plate "I.

Holes in the forward ends of the supports I89 (Fig. 14), which aredirectly beneath the pellets 95 when said pellet are in their forwardpositions, eliminate excessive surface tension between the bottom of thepellets and the top surface of the supports I89, to insure that saidpellets do not stick to said supports. Counter-clockwise movement of thesleeve I93, in unison with the plate "I (Fig. 18) and associatedmechanism, carries the pellet 95 in unison therewith. Near the end ofthis counter-clockwise movement, the conical-shaped boring I92 in thelower end of the sleeve I93 yieldingly engages the upper end of thecorresponding fuse 93, due to the action of the spring I94, toaccurately locate the counterboring 94 in saidfuse with the pellet 95,so that said pellet will be properly deposited in said counterboring.

After the pellet 95 has been deposited in the close the valve 205 toterminate the blast of air through the Venturi tube 203 (Fig. 15). Thistermination of the blast of air through the Venturi tube 203simultaneously terminates the suction in the tube 202 to effect thereleasing ofthe pellet 95, so that said pellet will remain in thecounterboring 94.

Return movement clockwise of the sleeve I93 (Fig. 18), in unison withthe plate "I, lifts the conical boring I92 clear of the nose of the fuse93, and, to insure that aid pellet does not stick in said boring, thetube I91 and its associated head I90, which have been forced upwardlyagainst the action of their spring I99 when the sleeve I93 engages theupper end of the fuse 93, as shown in Fig. 24, act as an ejector whensaid secured in a slide block 2I6. The slide block'2l6 is mounted forvertical sliding movement in a slot in an enlarged portion of theupright 44. The block 2I6 has threaded therein the lower end of aconnecting rod 2" with an enlarged head on the upper end thereof, whichcarries a pin 2I9 freely engaged by the lower ends of two identicallinks 2I9, which straddle the head portion of said rod 2". The links 2l9likewise straddle a beam 220, and theupper ends thereof are pivoted on apin 22I secured in said beam.

The rearward or right-hand end of the beam 220 (Fig. 20) is pivotallyconnected by a link 222 to a bracket formed by two angle bars 223, theforward ends of which are secured to a plate 224 in turn'secured to themain top plate 40. The rearward or right-hand ends of said bars 223 arefurther supported by a bar 225 extending between said bars and theupright 44.

The forward end of the beam 220 (Figs. 1, 20, and 21) has formed thereonan enlarged boss 226, which supports a pin 221- engaged by two similarupward extensions 220 of a connecting bracket 229. A base portion of thebracket 229 is secured. to the flat top surface of a main casting 230,which casting supports the four identical crimping heads forsimultaneously crimping over the upper ends of the four fuses 93, ineach of the five sets of fuses, as they arrive at station 4. The casting230 (Figs. 20 and 21) has two upright cylindrical portions havingtherein similar borings, which are a slip fit on guide pins MI and 232having tenons on the lower ends thereof secured in the plate 224.

' The mechanism shown in Fig. 6 revolves the gear I00 and the cam drum2I2 one revolution in Y a clockwise direction each time the turntable 41is dwelling in one of its five positions. Rotation of the cam 2I2, bymeans of the cam slot 2I3 in cooperation with the roller 2, shifts theslide 2 I5 first downwardly to crimp over the upper nds of the fuses 93,as will be explained more fully later, and then back to normal position,as shown in Fig. 20, according to the time given in space 4, Fig. 29.Downward movement of the casting 230 (Fig. 20) and the crimpingmechanism supported thereby, in addition to crimp ing the upper ends ofthe fuses 93, likewise causes a stamping mechanism, supported by each ofthe four crimping heads, to stamp identifying data on the outsidecircumference of the fuses 93.

A forward extension 233 (Fig. 20) of the upthe turntable 41 andasslsts'said' casting in sup porting the upper end of the spindle I93,and likewise supports the table 41 against the downward.

thrust of the crimping and stamping mechanisms. A thrust block 234,secured to a bottom surface of the extension 233, in cooperation with atempered thrust ring 235 inserted'in a recess -the time chart (Fig. 29),causes the boring 231 in the top face of the drum'2l2, assists thecasting 54in absorbing .the thrust load imposed on said drum 2l2 whenthe crimping and stamping mechanisms function.

The casting 239 (Figs. 1, and 26) supports. the four. crimping andstamping heads, all of which are exactly alike. A cross section-of onecrimping and stamping head is shown in Fig. 26

and will beused as representative-of all four heads in the followingdescription. v

The crimping and stamping mechanism shown in Fig. 26 comprises aninternal sleeve 236having a conical boring 231, which fits the contourof the fuse 93 to centrally locate the upper end of said fuse inrelation to a ring staking or crimping groove 238 in a rod 239, whichrod is a slip fit in a central boring in the'sleeve 236;

The internal sleeve 236 is a slip fit in a central boring in an externalsleeve 249 free in a boring in the casting 239. The sleeve 249 isadjustable vertically in said boring by means of a threaded bushing 2free on the external circumference thereof, and having threaded thereonan adlusting ring nut 242 adapted to engage thebottom surface of thecasting 239 to adjust. the sleeve 249 up or down in relation to theturntable 41 and the fuse 93. A clearance boring in the casting 239provides clearance for the vertical adjustment of the 'bushing 24!.

The upper end of the sleeve 249 is threaded to receive a threaded cap243 adapted to engage the top surface of the casting 239 to clamp thenut 242 against the bottom surface of said castin: to secure the sleeve249 and associated parts in set positions. The bushing 241 (Fig. 26),the

ring nut 242, and the cap 243 have in the peripheries thereof aplurality of spanner wrench holes to facilitate the adjustment and thetightening thereof. A screw stud 244 (Fig. 26),

in the sleeve 236 to engage the nose of the fuse 93 to centrally locatesaid fuse in relation to'the crimping groovev 238 in the rod 239."Immediately thereafter, the upper end of the rod 239 is contacted bythe end of the screw 241, which forces said rod downward y. causing thegroove 238 to engage and crimp over the upper end of the fuse 83, asshown at 96 (Fig. 25) to secure 'the pellet 95 in the counterboring 9'4.7 Upon return movement upwardly of the casting 239, the spring 246, incooperation with the collar 245 and-the rod 239, acts as an ejector toelect the crimped fuse 93 from the boring231.

' I "Stamping mechanism Simultaneousl with the crimping'of the upper endof the fuse 93 (Fig-26) mechanism, operated by downward movement ofthecasting 239, causes identifying data to be stamped or impressed on theperiphery of said fuse near the bottom edge thereof, aslindicated at 259(Fig. 25). I

A conical head portion 252 (Figs; 26 and 27) of the sleeve 236 hastherein a plurality of angular slots, each of which slidably supportsand threaded in the casting 239, has thereon a tenon 3 adapted tocooperate with vertical slots in the sleeves 249 and 236 to prevent theturning of said sleeves.

The rod 239 (Fig. 26) has secured thereto a collar 245 free in thecentral boring of the sleeve 249. A spring 246 fits freely in the boringin the sleeve 249 and around the rod 239,'and said spring is compressedbetween the collar 245 and a counterboring in the cap 243 to urge saidrod 239 downwardly. The upper end of the rod 239 cooperates with thelower end of an adjusting screw 241 threaded in the cap 243 and adaptedto be locked in adjusted position by a ring nut 248, threaded thereon,when said nut is tightened against the top face of said cap 243. Aplurality of spanner wrench holes are provided in the periphery of thering nut 248 and the periphery of the head of the screw 241 tofacilitate the turning and tightening of said parts.

The vertical slot in the sleeve 236 (Fig. 26) in cooperation with thetenon of the screw 244, determines the extent of the downward movementor position of rest of said sleeve and the crimping rod 239, underinfluence of the spring 246. A boring in thecenter of the screw 241freely supports a knockout pin 248, which is provided for manuallydriving down the rod 239 to eject L-shaped stamping member 253, and saidhead 252 likewise contains three wider slotswhich slidably support threeL-shaped equalizing bars 254, said bars being disposed Opposite thestamp-- ing members 253 and'working in conjunction therewith to equalizeand distribute the pressure on the fuse 93 during the stampingoperation.

The members 253 and the bars '254 are retained in the angular slots by acover plate or disk 255 secured to the'head 252 by a plurality ofscrews. Compressible springs 256 (Fig. 26) retained freely in angularholes in the conical head 252, engage upward legs 251 and 256 of therespective members 253 and 254 to urge said upward extensions intocontact with a tapered boring 259 in a head portion 269 of the externalsleeve 249.

Downward movement of the casting 239 and of the sleeve 249 causes thetapered boring 259, in cooperation with the upward legs 251 and 258, toforce the members 253 and the bars 254 inwardly against the action ofthe springs 256 to cause said members 253 to impress or stamp thedesired identifying data in the peripheryof the fuse 93 and to causesaid bars 254 to simultaneously engage the periphery of said fuse,opposite the stamping members 253, to equalize and distribute thestamping load.

When the boring 231 in the sleeve 236 (Fig. 26) properly engages theperiphery of the fuse 93 to locate said fuse in relation to the crimpinggroove 238, a horizontal surface on the downward face of the cap 255engages the top surface of the turntable 41 to sustain the downwardthrust imparted to said sleeve 236 by the stamping members 253 and theequalizing bars 254. The turntable 41 is assisted in sustaining thethrust load imposed by the sleeves 236 and 249 by the extension 233 ofthe upright 44 (Fig. 20), the supporting frame 54, and the block 234, incooperation with the washer 235 in the recess in the drum 2l2. Theseparts likewise sustain the upward thrust of the drum 212 during thecrimping and stamping operations.

Return movement upwardly of the casting 236 (Fig. 26 and space 4, Fig.29) retracts the tapered boring 259 from the upward legs 251 and 258 topermit the springs 256 to return the impression members 253 and theequalizing bars 254 outwardly out of engagement with the periphery ofthe fuse 93. Continued return movement upwardly of the casting 236causes the tenon f the screw 244 to engage the upper end of the slot inthe sleeve 236, to carry said sleeve upwardly in unison therewith. Thespace provided between the upper end of the sleeve 236 and the collar245 permits said collarand the rod 239 to remain stationary, underinfluence of the'spring 246, during'this period to eject the fuse 93from the tapered boring 231 in the sleeve 236.

Ejecting mechanism After the crimping and stamping operation has beencompleted, the Geneva gear mechanism shown in Figs. 6 and17 indexes theturntable 41 (Fig. 2) to transport the crimped fuses 93 from station 4to station 5, where, in the next cycle of operation, said fusesare-lifted out of the borings in the bushings 92 and deposited in achute which transports said fuses to a. suitable receptacle.

Referring now to Figs. 1, 5, and 28, the gear l6! has integral therewitha drum portion 26f having formed therein a camming groove 262 engaged bya roller 263 rotatably mounted on a pin secured in a slide 264 mountedfor vertical sliding movement in a slot in a casting 265 secured to theupright 45. The slide 264 has secured to the upper end thereof a crossbar 266 having secured in opposite ends thereof two identical rack bars261 and 268.' The rack bars 261 and 268 (Figs. 1, 2, 5, and 28) extendvertically through clearance holes in the top plate 46 and areslidablysupported, respectively, in vertical slots formed in uprights 269 and216 secured to the top plate 46. The rack bars 261 and 268 are retainedin their respective slots by cover plates 211 and 212 secured,respectively, to the uprights 269 and 216, which cover plates giveaccess to said rack bars and to their associated gears.

The teeth in the rack bar 261 (Figs. 2 and 28) mesh with the teeth insimilar companion gears 213 and 214, said gear 213 being secured on ashort shaft 215 journaled in the upright 216, and said gear 214 beingsecured on one end of a shaft 216 extending-between the uprights 269 and216 and having opposite ends journaled therein. The rack bar 268 mesheswith companion gears, similar to the gears 213 and 214, securedrespectively to a short shaft 211 (Fig. 2) in axial alinement with theshaft 215 and journaled in the upright 269, and said gear correspondingto the gear 214, being secured on the opposite end of the shaft 216. Thegears 213 and 2.14 and their companion gears revolve respectively inclearance recesses formed in the uprights 269 and 216, which recessesare covered by the plates 2H and 212.

Secured, respectively, on the short shafts 215 and 211 (Figs. 2 and 28),and between the uprights 269 and 216, are companion arms 218 and 219.Also, secured near opposite ends of the shaft 216 and between theuprights 269 and 216, are companion arms 280 and 28L Companion links 282and 283 (Figs. 2 and 28) connect the outer.

ends of the pairs of arms 218 and 219, and 286 and 28l, for unitaryparallel movement. The upper ends of the links 282 and 283 are pivotedbushings having threaded tenons which extend through borings in said bar286. Nuts 289, in cooperation with the upper ends of the threadedtenons, secure the bushings 288 in place on said bar 285. The bushings288 have therein tapered borings 296, which conform to the shape of .the

noses of the fuses 93. Each of the bushings 288 has three equally spacedslots-in the periphery thereof, each Of which slots supports afuseejecting hook 29! pivoted on a pin 292 in said bushing. Each of thebushings 288 has a compressible spring 293, which loosely. encircles anundercut portion thereof, said spring being compressed between ashoulder formed by said undercut portion and shoulders. formed on thehooks 29l. The springs 293 urge the hooks 29! toward the center of thebushing 288 to normally maintain the fuse-engaging notches in the insideedges of extensions 294 of said hooks in engagement with a shoulderformed by a threaded tenon on the fuses 93 for the purpose of electingsaid fuses from the holes in the bushings 92.

Each of the bushings 92 (Figs. 2, 12,- and 28) has in the upper edgesthereof three equally spaced notches 295 to provide clearance for theextensions 294 of the hook 29l when said hooks engage the shouldersofthe fuses 83, as shown in Fig. 28. Dowel pins 291 (Fig. 2), whichextend through matching holes in the bar 285 and-the heads of thebushings 288, prevent the turning of said bushings and thereby maintainthe extensions 294 of the hooks 29] in alinement with the notches 295.Each of the bushings 288 (Fig. 28) has a spring-pushed ejector plunger298, which fits freely in a central boring in said bush ing, eachplunger having a head 299 which is urged into contact with the pellet95, secured in the nose of the fuse. 93, by a compressible springt'ensioned between said head and a shoulder formed by a counterboring insaid bushing 288, which counterboring likewise provides clearance forthe head 299. Secured on the upper ends of each of theplungers 298 is acollar 366, which, in cooperation with the upper ends of the threadedtenons on the bushings 288, determines the extent of the downwardmovement of said 1) in the drum 261 is'given in space 5 of the timechart (Fig. 29), from which it will be seen that, at the beginning ofeach of the five stages of an operating cycle. the fuse-ejectingmechanism is in the positions shown in Figs. 1 and 2, after having justcompleted the ejection of four of the time fuses 93. This position ofthe ejecting mechanism is also indicated by the dot-and-dash showing ofone of the bushings 288 and one of the hooks 29! in Fig. 28.

Initial movement of the gear IM and the drum 26! (Figs. 1, 2, 5, and 28)causes the can! groove 262, in cooperation with the roller 263, to shiftthe racks 261 and 268 upwardly to rotate the gears 213 and 214, theshafts 215,- 211, and 216, and the corresponding arms 218, 219, 286, and28f clockwise, as viewed in Fig. 1, through an arc of approximatelylsodegrees. The parallel movea,s7o,sas

to secure the peliets ln said counterborings. At

ment of the two pairs of arms 219 and 219 and 290 and 29! causes thelinks 292 and 299, the

bar 295, and the bushings 299 to be maintained in vertical position, asshown here, throughout the entire movement of the ejecting mechanism ineither direction.

During initial movement clockwise of ing mechanism, the turntable 41 isindexedby the Geneva gear mechanism, shown in Figs. 6

'and 16, to bring the next set of finished fuses 93 the eject- I objectsprimarily stated, it is to be understood" 7 the fifth or final station,the finished fuses are "lifted from the recesses in the turntable andiieposited in a chute which transports said fuses to a suitablereceptacle.

It is believed that further description of the operation of the machineis unnecessary, as a full understanding thereof will have been obtainedlo from a perusal of the preceding specification.

While the form of mechanism herein shown and described is admirablyadapted to fulfill the that it is not intended to confine the inventionto the one form or embodiment herein disclosed, for it is susceptible ofembodiment in various forms all coming within the scope of the claimswhich follow.

What is claimed is:

1." In a machine of the class described for assembling elements intoarticles of manufacture, the combination of a magazine for storing the Ielements; a table; a guide on said magazine conchart. Fig. 29)returnsthe ejecting mechanism,

including the bar 285 (Fig. 28) and the bushings 288, counter-clockwise,causing said bushings, in cooperation with said hooks 29l, to lift thefuses 93 out of the borings in the bushings 92 and to transport saidfuses, in ferris-wheel fashion, into alignment with the borings in fourbushings 3M secured in the top plate 49. As the completed fuses 93 enterthe borings in the bushings 30!, angular surfaces on downwardlyextending fingers 302 of the hooks ,29l engage a tapered surface 303formed on the upper ends of the bushings 3M and are rocked by saidsurfaces away from t"'e center of the bushings 288 against the action ofthe springs 293, to disengage the notches in the hooks 29! from theshoulders of the fuses 93. After the hooks 29l have thus beendisengaged, the spring plungers 298, which are under tension at thistime, eject the fuses 93 downwardly out of the conical borings- 299 inthe bushings 289, thereby causing said fuses to drop through the boringsin the bushings 3M and into a chute 309 secured to the bottom surface ofthe top plate 49, which chute directs said finished fuses to a suitablereceptacle. The extent of the inward movement of the hooks 29i (Fig.28), under influence of the springs 293, is determined by the bottom ofthe corresponding slots in the bushings 289, in

cooperation with the fiat surfaces on the inner edges of said hooks, toretain said hooks in proper position to snap over the shoulders of thefuses 93 near the end of the initial movement of the ejecting mechanism,as explained above.
